L&S Air | Certified HVAC Repair in San Juan, TX

In San Juan's climate, we frequently handle issues like faulty thermostat wiring, which can cause your system to short-cycle or not turn on at all, and failed AC capacitors, which are a common reason for compressors not starting. Our technicians are experienced in diagnosing and resolving these local, weather-related problems efficiently to restore your cooling quickly.

Regular maintenance is crucial for preventing unexpected breakdowns, especially during our hot South Texas summers. Our maintenance service includes cleaning, inspecting, and tuning up your system. This proactive care helps your HVAC run more efficiently, lowers energy bills, extends the system's lifespan, and often catches small issues—like a weakening capacitor—before they turn into costly, emergency repairs.

Our installation process begins with a detailed assessment of your home's size, layout, and your family's comfort needs to recommend the right system. Our licensed technicians handle the entire replacement with precision, from safely removing the old unit to installing and testing the new one. We ensure proper setup for maximum efficiency and longevity, and we stand behind our work with a guarantee on the installation.
